Salesforce Org has two companies using it - where one is a wholly owned subsidiary of the other. We now need to enable My Domain for Lightning components to work and have a business request that we have a different domain name for each of the two companies in the same SF org, e.g. company1-my-salesforce.com and childcompany.my.salesforce.com with users distinguished by profile and/or role.
Looking at the documentaion and setup page it appears that a maximum number of 1 domiain is supported for login of internal users on the full Salesforce lenience. Is there any meanse of working around this?
